Tire tread



FIG. 1 is a front right perspective view of a tire tread, showing my new design, it being understood that the tread pattern repeats uniformly throughout the circumference of the tread;

FIG. 2 is a front elevational view thereof; and,

FIG. 3 is a side elevational view thereof, the opposite side elevational view being a mirror image thereof.

The broken line showing of the tire sidewall in the drawings is for illustrative purposes only and forms no part of the claimed design. 

The ornamental design for a tire tread, as shown and described.
